Brief Summary

This is a three-period, three sequence, reference replicated, cross-over study to determine the bioequivalence of two amlodipine and losartan FDC tablet formulations FDC5/50 and FDC5/100 (GSK2944406; 5 mg amlodipine and 50 mg and 100 mg losartan) to reference amlodipine and losartan tablets co-administered in two groups enrolling 102 healthy adult male and female subjects under fasting conditions.

A description of each treatment is provided below:

A (Reference) = 1 x 5 mg amlodipine tablet and 1 x 50 mg losartan tablet. B (FDC5/50) = 1 x 5 mg amlodipine and 50 mg losartan tablet C (Reference) = 1 x 5 mg amlodipine tablet and 1 x 100 mg losartan tablet D (FDC5/100) = 1 x 5 mg amlodipine and100 mg losartan tablet The treatments will be administered in accordance with the randomisation schedule as.

Group 1: A → A → B or A → B → A or B → A → A Group 2: C → C → D or C → D → C or D → C → C All subjects will attend a screening visit within 28 days of their first dosing period (Day 1). The baseline assessments will be conducted the day before the first dosing.

In each treatment period, subjects will be admitted to the clinic in the evening before Day 1. All subjects will receive a single oral dose of amlodipine and losartan in the morning on Day 1. All the subjects will remain in the clinical unit until completion of all assessments at 24 hours post-dose on Day 2 including collection of the 24 hour post-dose PK sample. Subjects will return to the clinic for pharmacokinetic samples at 36, 48, 72 and 96 hours post-dose.

The three treatment periods will be separated by a washout period of 10-17 days. Upon completion of the last dosing period, or early withdrawal, subjects will return to the clinical unit within 14-21 days for a follow up visit.

FDC 5/50 amlodipine/ losartan

Intervention Type: DRUG

Subjects will receive single oral dose of 1 tablet containing 5 mg amlodipine and 50 mg losartan in fasted state

Group 2 (5 mg amlodipine and 100 mg losartan)

Subjects in Group 2 will be randomized to receive a single dose FDC 5/100 mg; and also separate single tablets each of reference treatment 5 mg amlodipine and 100 mg losartan. The reference treatment will be replicated in a three sequence, three period design

Group Type: EXPERIMENTAL
